Description

Technical Field

[0001] The present invention belongs to the technical field of steel shot production, and specifically relates to a stainless steel shot rounding machine. Background Art

[0002] Stainless steel shot is a kind of metal abrasive, which is made into spherical particles through special heat treatment. It is mainly used for descaling, rust removal and surface cleaning. It is widely used in the surface treatment of castings, forgings, machined parts, and the surface treatment of parts after heat treatment and other fields. When rounding stainless steel shot, the stainless steel shot blank is poured into the rounding machine. After the rounding machine starts, the transmission system drives the rounding disc to rotate at a high speed. After the material is fed into the rounding machine, under the action of the rotation of the rounding disc, it continuously tumbles and collides inside the rounding machine, making the material gradually become more round and reach the required shape and surface quality.

[0003] In the prior art, when discharging materials after the rounding work is completed, the discharge door on the side of the equipment is opened, and the steel shot is thrown out under the action of centrifugal force. Since the magnitude of the centrifugal force is related to factors such as the mass, rotational speed and radius of rotation of the particles, the centrifugal forces received by different particles during the rounding process may be different, which makes it difficult to accurately control the speed and quantity of the particles during discharging, and thus the discharge quantity may be unstable.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 5 shown, a stainless steel shot rounding machine according to an embodiment of the present invention includes a workbench 1. A rounding barrel 2 is fixedly installed on the top of the workbench 1. A rounding disc 3 is rotatably installed on the inner wall of the rounding barrel 2. A driving assembly is arranged at the bottom of the rounding disc 3. A material collecting box 4 is slidably installed on the inner wall of the rounding barrel 2. A cylinder 5 is arranged on one side of the rounding barrel 2. The output shaft of the cylinder 5 is fixedly installed with a connecting arm 11. One end of the connecting arm 11 away from the cylinder 5 is fixedly connected to the outer wall of the material collecting box 4. A blanking assembly is arranged below the material collecting box 4; when performing rounding work, stainless steel shot blanks are poured into the interior of the rounding barrel 2, and then the driving assembly is started. The driving assembly drives the rounding disc 3 to rotate at a high speed. The high-speed rotating rounding disc 3 will drive the stainless steel shot blanks to move in the rounding barrel 2, and rounding work is carried out through continuous tumbling and collision. When the rounding work is completed, the rounding disc 3 stops rotating. At this time, the cylinder 5 is started. The cylinder 5 pushes the material collecting box 4 into the interior of the rounding barrel 2 through the connecting arm 11. Then the rounding disc 3 is rotated again. The opening length of the material collecting box 4 is greater than the inner circle radius of the rounding barrel 2. When the rounding disc 3 rotates, it will drive the stainless steel shot to enter the interior of the material collecting box 4 from the opening of the material collecting box 4 and gather. After the stainless steel shot gathers in the interior of the material collecting box 4, the cylinder 5 extends to move the material collecting box 4 out of the interior of the rounding barrel 2. The moved material collecting box 4 is located above the blanking assembly. The stainless steel shot in the material collecting box 4 will be discharged through the blanking assembly, ensuring the effectiveness of discharging, thereby solving the problem of unstable discharging of existing equipment during discharging and making the discharging effect of the device better.

[0023] As Figures 1 to 5As shown, the blanking assembly includes a blanking hopper 6. A support frame 7 is fixedly installed at the top of the blanking hopper 6. The outer walls of both the support frame 7 and the blanking hopper 6 are fixedly connected to the outer wall of the rounding barrel 2. The bottom of the material collecting box 4 is slidably connected to the top of the support frame 7. A sealing baffle 8 and a limiting strip 9 are fixedly installed at the top of the support frame 7. The outer walls of both the sealing baffle 8 and the limiting strip 9 are slidably connected to the outer wall of the material collecting box 4. When the material collecting box 4 moves, it will slide above the support frame 7. When the material collecting box 4 is moved out of the rounding barrel 2, the sealing baffle 8 will block the opening of the material collecting box 4, so that when the material collecting box 4 is located outside the rounding barrel 2, the stainless steel shots cannot leak out from the opening of the material collecting box 4. The limiting strip 9 limits the material collecting box 4 in cooperation with the sealing baffle 8 to ensure that the material collecting box 4 moves along the preset direction. The blanking hopper 6 is located above the support frame 7. When the material collecting box 4 is moved out of the rounding barrel 2, the stainless steel shots in the material collecting box 4 will pass through the support frame 7 and fall to the inside of the blanking hopper 6. The stainless steel shots that fall to the inside of the blanking hopper 6 will finally be discharged along the blanking hopper 6, thus achieving the effect of discharging materials.

[0024] As Figures 1 to 6 shown, a discharge box 10 is slidably installed on the inner wall of the material collecting box 4. A filter screen 12 is detachably installed on the bottom inner wall of the discharge box 10. When discharging materials, the stainless steel shots will gather in the material collecting bin formed by the material collecting box 4 and the discharge box 10. At this time, the stainless steel shots are located on the filter screen 12. When the material collecting box 4 is moved to the outside of the rounding barrel 2, the air cylinder 5 will reciprocally extend and retract to drive the material collecting box 4 to swing reciprocally. By the reciprocal swinging of the material collecting box 4, the internal stainless steel shots are in a moving state. When the stainless steel shots are moving, the stainless steel shots that meet the specifications will pass through the filter screen 12 and be successfully discharged, while the stainless steel shots that do not meet the specifications will stay above the filter screen 12, thus achieving the effect of screening the stainless steel shots. It should be noted that the filter screen 12 is detachable and can be replaced with different specifications of filter screens 12 according to production requirements, or the filter screen 12 can not be used.

[0025] As Figures 5 to 8As shown in the figure, two sets of gears 13 are arranged inside the discharging box 10. A stirring shaft 14 is fixedly installed on the inner wall of each gear 13. One end of the stirring shaft 14 is rotatably connected to the inner wall of the top of the discharging box 10. The teeth of two gears 13 in each group are meshed with each other. A rack 15 is fixedly installed on the outer wall of the sealing baffle 8. The teeth of one of the gears 13 in each group are meshed with the teeth of the rack 15. A stirring rod 16 is fixedly installed on the inner wall of the stirring shaft 14; after the material collecting box 4 is moved out of the rounding barrel 2, one of the gears 13 in each group will be meshed with the rack 15, and at the same time, the gears 13 in each group are meshed with each other. Therefore, when the material collecting box 4 moves outside the rounding barrel 2, the gear 13 will rotate through the cooperation with the rack 15. When the gear 13 rotates, it will drive the stirring rod 16 to rotate through the stirring shaft 14. When the stirring rod 16 rotates, it will stir the stainless steel shot, increasing the movement form of the stainless steel shot, so as to better carry out the screening work.

[0026] As Figures 5 to 9 shown in the figure, a positioning shaft 17 is fixedly installed on the inner wall of the discharging box 10. The outer wall of the positioning shaft 17 is rotatably connected to the inner wall of the material collecting box 4. One end of the positioning shaft 17 and located outside the material collecting box 4 is fixedly installed with a force receiving plate 18. A pushing assembly is arranged on one side of the material collecting box 4 close to the force receiving plate 18; when discharging, the qualified stainless steel shot will pass through the filter screen 12, and the unqualified stainless steel shot cannot pass through the filter screen 12, so it will stay above the filter screen 12. At this time, the material collecting box 4 is pushed into the rounding barrel 2 again through the air cylinder 5, and then the force receiving plate 18 is pushed through the pushing assembly. After the force receiving plate 18 receives the thrust, it will rotate around the positioning shaft 17. When the force receiving plate 18 rotates, it will drive the positioning shaft 17 to rotate. When the positioning shaft 17 rotates, it will drive the discharging box 10 and the filter screen 12 to rotate together. After rotation, the discharging box 10 and the filter screen 12 are in an inclined state, and the unqualified stainless steel shot will slide back into the rounding barrel 2 under the action of gravity, so as to achieve the effect of re-rounding the unqualified stainless steel shot.

[0027] As Figures 5 to 9 shown in the figure, the pushing assembly includes a receiving plate 19 fixedly installed on the outer wall of the material collecting box 4. An arc-shaped telescopic rod 20 is fixedly installed on the top of the receiving plate 19. A elastic force assembly is arranged between the end of the arc-shaped telescopic rod 20 far away from the receiving plate 19 and the force receiving plate 18; when the pushing assembly works, the arc-shaped telescopic rod 20 will extend. When the arc-shaped telescopic rod 20 extends, it will push the force receiving plate 18 to rotate through the elastic force assembly, so that the discharging box 10 and the filter screen 12 are inclined to pour the unqualified stainless steel shot back into the rounding barrel 2 for rounding.

[0028] As Figures 5 to 9As shown in the figure, the elastic component includes a sliding shaft 21. One end of the sliding shaft 21 is fixedly connected to the outer wall of the force-bearing plate 18, and the other end of the sliding shaft 21 is slidably connected to the inner wall of the arc-shaped telescopic rod 20. An elastic member 22 is fixedly installed between the arc-shaped telescopic rod 20 and the force-bearing plate 18 and on the outside of the sliding shaft 21. An elastic impact block 23 is fixedly installed on the side of the force-bearing plate 18 away from the sliding shaft 21. A positioning plate 24 is fixedly installed on the outer wall of the material collecting box 4, and an elastic force-bearing block 25 is fixedly installed on the outer wall of the positioning plate 24. When the force-bearing plate 18 rotates under the action of the arc-shaped telescopic rod 20, the elastic impact block 23 will collide with the elastic force-bearing block 25. Both the elastic impact block 23 and the elastic force-bearing block 25 are made of elastic materials, so as to prevent damage to the device during collision. When a collision occurs, the elastic member 22 will expand and contract under the action of inertia, so that the discharge box 10 and the filter screen 12 will vibrate. Through the vibration, the stainless steel balls can enter the rounding barrel 2 faster, and at the same time, the stainless steel balls stuck on the filter screen 12 can be shaken out to prevent material jamming.

[0029] As Figures 1 to 2 shown in the figure, the driving component includes a motor 26 located below the workbench 1. A driving shaft 27 is fixedly installed at the bottom of the rounding disc 3. The driving shaft 27 passes through the rounding barrel 2 and the workbench 1. Transmission wheels 28 are fixedly installed on the output shaft of the motor 26 and the outer wall of the driving shaft 27, and a transmission belt 29 is installed between the two transmission wheels 28 for transmission. When performing rounding work, the motor 26 will drive the driving shaft 27 to rotate through the action of the transmission wheels 28 and the transmission belt 29. When the driving shaft 27 rotates, it will drive the rounding disc 3 to rotate. The high-speed rotating rounding disc 3 will drive the stainless steel ball blanks to move in the rounding barrel 2, and perform rounding work through continuous tumbling and collision.

[0030] As Figures 1 to 2 shown in the figure, a fixing seat 30 is fixedly installed at the bottom of the workbench 1. An installation frame 31 and a positioning disc 32 are fixedly installed inside the fixing seat 30. The motor 26 is fixedly installed on the top of the installation frame 31. One end of the driving shaft 27 is rotatably connected to the inner wall of the positioning disc 32. The fixing seat 30 is used to fix the positions of the installation frame 31 and the positioning disc 32. The motor 26 is fixed by the installation frame 31 so that the motor 26 can provide power for the rounding work. The positioning disc 32 positions one end of the driving shaft 27 away from the rounding disc 3, increasing the stability of the driving shaft 27 during rotation.

[0031] As Figure 1As shown in the figure, a lid 33 is fixedly installed on the top of the round shot blasting barrel 2, a support base 34 is fixedly installed on the top of the workbench 1, a cylinder 5 is fixedly installed on the inner wall of the support base 34, and support legs 35 are fixedly installed at the four corners of the bottom of the workbench 1; the lid 33 is provided to prevent the stainless steel shot from flying out of the round shot blasting barrel 2 under the action of centrifugal force, the support base 34 is used to fix the cylinder 5 and provide a fulcrum for the cylinder 5, and the support legs 35 support the entire device, making the device at an appropriate working height and increasing the overall stability of the device.

[0032] Working principle: When performing the round shot blasting work, pour the stainless steel shot blank into the inside of the round shot blasting barrel 2, and then start the drive assembly. The drive assembly drives the shot blasting disc 3 to rotate at a high speed. The high-speed rotating shot blasting disc 3 will drive the stainless steel shot blank to move in the round shot blasting barrel 2, and perform the round shot blasting work through continuous tumbling and collision. When the round shot blasting work is completed, the shot blasting disc 3 stops rotating. At this time, start the cylinder 5. The cylinder 5 pushes the material collecting box 4 into the inside of the round shot blasting barrel 2 through the connecting arm 11. Then, rotate the shot blasting disc 3 again. The opening length of the material collecting box 4 is greater than the inner radius of the round shot blasting barrel 2. When the shot blasting disc 3 rotates, it will drive the stainless steel shot to enter the inside of the material collecting box 4 through the opening of the material collecting box 4 and gather. After the stainless steel shot gathers inside the material collecting box 4, the cylinder 5 extends to move the material collecting box 4 out of the inside of the round shot blasting barrel 2. The moved material collecting box 4 is located above the blanking assembly. The stainless steel shot in the material collecting box 4 will be discharged through the blanking assembly, thus solving the problem of unstable discharging of the existing equipment during discharging and making the discharging effect of the device better.

[0033] During the discharging work, the stainless steel shot will gather in the material collecting bin formed by the material collecting box 4 and the discharging box 10. At this time, the stainless steel shot is located on the filter screen 12. When the material collecting box 4 moves to the outside of the round shot blasting barrel 2, the cylinder 5 will reciprocate telescopically to drive the material collecting box 4 to swing reciprocally. Through the reciprocal swing of the material collecting box 4, the stainless steel shot inside is in a moving state. When the stainless steel shot is moving, the stainless steel shot that meets the specifications will pass through the filter screen 12 and be successfully discharged, while the stainless steel shot that does not meet the specifications will stay above the filter screen 12, thus achieving the effect of screening the stainless steel shot. It should be noted that the filter screen 12 is detachable and can be replaced with different specifications of filter screens 12 according to production needs, or the filter screen 12 can be not used. After the material collecting box 4 is moved out of the round shot blasting barrel 2, one gear 13 in each group will mesh with the rack 15, and at the same time, the gears 13 in each group mesh with each other. Therefore, when the material collecting box 4 moves outside the round shot blasting barrel 2, the gear 13 will rotate through the cooperation with the rack 15. When the gear 13 rotates, it will drive the stirring rod 16 to rotate through the stirring shaft 14. When the stirring rod 16 rotates, it will stir the stainless steel shot, increasing the movement form of the stainless steel shot, so as to better perform the screening work.

[0034] When carrying out the blanking work, the qualified stainless steel shots will pass through the filter screen 12. Since the unqualified stainless steel shots cannot pass through the filter screen 12, they will remain above the filter screen 12. At this time, the material collecting box 4 is pushed into the rounding barrel 2 again by the air cylinder 5. Then, the force receiving plate 18 is pushed by the pushing assembly. After receiving the thrust, the force receiving plate 18 will rotate around the positioning shaft 17. When the force receiving plate 18 rotates, it will drive the positioning shaft 17 to rotate. When the positioning shaft 17 rotates, it will drive the blanking box 10 and the filter screen 12 to rotate together. After rotation, the blanking box 10 and the filter screen 12 are in an inclined state. The unqualified stainless steel shots will slide down back into the rounding barrel 2 under the action of gravity, so as to achieve the effect of re-rounding the unqualified stainless steel shots. When the pushing assembly is working, the arc-shaped telescopic rod 20 will extend. When the arc-shaped telescopic rod 20 extends, it will push the force receiving plate 18 to rotate through the elastic force assembly, so that the blanking box 10 and the filter screen 12 are inclined to pour the unqualified stainless steel shots back into the rounding barrel 2 for rounding. When the force receiving plate 18 rotates under the action of the arc-shaped telescopic rod 20, the elastic impact block 23 will collide with the elastic force receiving block 25. Both the elastic impact block 23 and the elastic force receiving block 25 are made of elastic materials, so as to prevent damage to the device during collision. When a collision occurs, the elastic member 22 will expand and contract under the action of inertia, so that the blanking box 10 and the filter screen 12 vibrate. Through vibration, the speed of the stainless steel shots entering the rounding barrel 2 can be increased, and at the same time, the stainless steel shots stuck on the filter screen 12 can be shaken out to prevent material jamming.
